向煤中添加木质素是协同的，因为它显著提高了在中等压力和温度条件下由煤生产的液体产物的质量和产率（高达33%）。例如，通过在325 ° C下木质素辅助解聚煤获得的液体含有明显较低量的不期望的高分子量苯不溶性化合物，以及较高量的期望的较低分子量沥青质和戊烷可溶性级分，其相对于通过在相同条件下加工煤或木质素获得的液体中的相应级分。实验结果表明，木质素除了具有上述助解聚作用外，还具有提高煤解聚反应稳定性的作用
Addition of lignin to coal is synergistic in that it significantly improves the quality and yield (by up to 33%) of the liquid products produced from coal under moderate pressure and temperature conditions. For example, the liquids obtained by lignin-assisted depolymerization of coal at 325 o C contain appreciably lower amounts of the undesirable high molecular weight benzene-insoluble compounds, and higher quantities of the desirable lower molecular weight asphaltenes and pentane-soluble fractions over the corresponding fractions in liquids that are obtained by processing either coal or lignin under identical conditions. The experimental data conclusively show that, in addition to the favorable influences of the lignin-assister depolymerization listed above, lignin also enhances the stability of the coal depolymerization reaction
